在Ubuntu上安装pyenv 相关问题Common build problems

Requirements:

Ubuntu/Debian:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \

libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils

Fedora/CentOS/RHEL:

FIXME: you may need to install xz to build some CPython version

yum install zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel

Mac OS X:

brew install readline xz

NOTE: libssl-dev is required when compiling Python, installing libssl-dev will actually install zlib1g-dev, which leads to uninstall and re-install Python versions (installed before installing libssl-dev). On Redhat and derivatives the package is named openssl-devel.

Removing a python version

rm -rf ~/.pyenv/versions/2.7.5

Installing a 32 bit python on 64 bit Mac OS X (this will not work on Linux)

CONFIGURE_OPTS="--with-arch=i386" CFLAGS="-arch i386" LDFLAGS="-arch i386" python-build options

Installing a system-wide Python

If you want to install a Python interpreter that's available to all users and system scripts (no pyenv), use /usr/local/ as the install path. For example:

sudo python-build 3.3.2 /usr/local/

Make your pythons a little faster

You can set your CFLAGS to accepted safe values to help get a little more speed.

CFLAGS='-O2'

Build failed - bad interpreter: Permission denied

If you encounter this error while installing python and your server is a VPS, the /tmp directory where python-build download and compile the packages is probably mounted as noexec. You can check with your hosting provider if wether they provide a way to bypass this protection.

If the answer is no, just set the $TMPDIR environment variable to wherever you have a write + execution rights. For example:

export TMPDIR="$HOME/src"

Please note you'll have to do it every time you'll want to install a new version of python unless you write this command in your ~/.bashrc.

Build failed

If you've got something like that:

$ pyenv install 2.7.5

Installing yaml-0.1.4...

BUILD FAILED

Please, be sure to have "make" installed ($ sudo apt-get install make). On Ubuntu Server, by default, it doesn't.

Build failed: "ERROR: The Python zlib extension was not compiled. Missing the zlib?"

Installing Python-2.7.7...

ERROR: The Python zlib extension was not compiled. Missing the zlib?

Please consult to the Wiki page to fix the problem.

BUILD FAILED

On Mac OS X 10.9, 10.10 and 10.11 you may need to set the CFLAGS environment variable when installing a new version in order for configure to find the zlib headers (XCode command line tools must be installed first):

CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7

Alternatively, try reinstalling XCode command line tools for your OS (especially if you just upgraded your OS)

xcode-select --install

ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

If you have homebrew openssl and pyenv installed, you may need to tell the compiler where the openssl package is located:

CFLAGS="-I$(brew --prefix openssl)/include" \

LDFLAGS="-L$(brew --prefix openssl)/lib" \

pyenv install -v 3.4.3

or (checked on RHEL6):

CFLAGS=-I/usr/include/openssl \

LDFLAGS=-L/usr/lib64 \

pyenv install -v 3.4.3

Alternatively, if you installed openssl with macports, use the following paths:

CFLAGS="-I/opt/local/include/" \

LDFLAGS="-L/opt/local/lib/" \

pyenv install -v 3.4.3

On FreeBSD 10-RELEASE and 11-CURRENT, you may need to recompile security/openssl without SSLv2 support. (See #464).

python-build: definition not found

To update your python-build definitions:

If you have python-build installed as an pyenv plugin:

$ cd ~/.pyenv/plugins/python-build && git pull
